说明：
    1：在条码文本框输入想要生成条码的内容，点击生成按钮（快捷键enter或者tab）生成条码。
    2：为方便扫码后查看历史条码，条码可以无限生成，排在最上面的条码永远是最新的条码。
    3：点击重置按钮（快捷键delete或者home）将会刷新整个页面，已经生成的条码将会清空，此操作不可逆。
    4：形状类型分A、B、C、3种，默认使用B类型，也是最实用的类型，可以输入数字和英文字符，如果发现生成的二维码跟实际不符合，可以切换形状类型后尝试。
    5：点击生成按钮后，条形码文本框自动全选，方便输入下一个条形码。
    6：本代码紧做参考，如需扩展请自行修改html源码，源码中都有相应注释。
